Laboratory Study of the Shear Behaviour of Natural Rough Rock Joints Infilled by Different Soils
Natural rock joints infilled with soil materials may show a reduced shear strength, which influences rock mass stability. The aim of this paper is to experimentally investigate the shear behaviour of infilled rock joints, taking into account joint surface characteristics and the properties of the joint and infill materials. A new model for predicting the shear strength of infilled joints is pre...
متن کاملShear Strength of Rock Joints Based on Quantified Surface Description
One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

متن کاملShear Viscosity under Shock-Loading Conditions
Although we rarely see a shock wave in everyday life, we experience them upon hearing the sound of an explosion, the bang of a gunshot, or the crack of a whip. In addition, objects that travel at supersonic speeds, such as bullets and missiles, also generate shock waves. During a typical shock-loading process, large pressures generated at the shock front can lead to an increase in the reactants...
متن کاملLaboratory and Numerical Modelling of a Jointed Rock Mass
Laboratory tests were performed on 54 large size specimens of jointed rock mass under uniaxial loading conditions. Based on this experimental study, a methodology has been suggested to estimate strength and tangent modulus of rock masses through a weakness coefficient. The methodology involves mapping of joints in the field and laboratory testing of intact rock specimens to arrive at rock mass ...
